Pricing
We do not reprint prices. They change too often for that to be honest, and a number on our page with no date is worse than sending you to the source.
How we rated it
What it is
Text-to-speech built for very low latency, intended for real-time conversation rather than narration — voice agents, phone systems, live assistants.
Who it is for
Developers building something people talk to, where a pause before the reply breaks the illusion.
Where it is strongest
Voice agents. The latency is low enough that a conversation feels like one, which is the single thing that determines whether people tolerate it.
Where it falls short
Narrower voice range and less expressive than ElevenLabs. A smaller language catalogue. And it is built for one use — for narration or audiobooks it is the wrong tool.
Our verdict
Recommended for real-time voice. For anything pre-recorded, ElevenLabs sounds better and the latency does not matter.
